Be it known I that; I,-IJAims -K. R cnm,

The present invent'ionappertains to steelyards or balance scales, and. aims to"pro portion of the beam 1 adjacent the zero graduation. .This poise 4 is heldin any vide a novel and improved balance scaleutiadjustable poise, Wherebv the beam can be shifted relative to. its fulcrum, the poise being carried in a fixed 'position upon the beam; so that the weight of the beam is utilized in connection with the poise foreb- Itis also withi'nthe v tion to provide in abalance scales, novel and. improved details of constriution; to'v enhance the utility and efficiency of the dea vice. thedevice being comparatively simple, lightg compact and inexpensivein ;'eonstri1c-' tion, being." constructed largelyfofgsheet metal. stampings, and;being thorpughly ;praeti.cal, serviceable," reliable and I. convenient in'u'seQ v -iWith the foregoing and other objects in view which'will appeara's the description proceeds, the invention resides; in the com j'bination and arrangement of parts and-in ithe detailsof constructionhereinafter described and claimed, it; being iinderstood amt-ch nges inthe precise embodiment of the invention herein disclosed can be made within the scope of what is claiined without damnin from the spirit. of thei invention.
